When you arrive at the hotel, you do not need to hand over your credit card. The hotel will have access to your credit card details in order to charge the room night costs. On the day of your departure, if you have consumed any additional services or items from the minibar for example, the hotel will charge your credit card once again. You do not need to be present for this process. You will receive a transaction receipt via email for each transaction made, in addition to the invoice you receive on the day you depart.
